[Compatibilité matériel Haswell] Message inquiétant !
Bonjour,
J'ai un laptop à base de processeur Haswell, le circuit vidéo est intégré...
Régulièrement j'ai la trace du noyau suivante :

Il m'est arrivé plusieurs bug d'affichage et plusieurs freeze complets...
Est-ce qu'il y a des solutions de contournement ?
